Daily Evil Sudoku

The daily evil sudoku starts from the proven minimum of 17 givens — the mathematically smallest number that still produces a unique-solution 9×9 puzzle. A fresh puzzle every visit means the daily evil is genuinely a daily trial. Solving an evil-tier sudoku in under an hour puts you in the top tier of solvers anywhere online; most players need more than that, and that's expected. Every move has a logical justification, but the chains of inference are long and the forks are deep. This tier rewards patience, careful pencil marks, and the kind of deductive stamina that comes from solving thousands of puzzles. If the evil daily feels too punishing, drop back to master or expert and build up. Create a free account to save evil solve times — they're the metric serious solvers compare.
